I have an escort passport 8500 x50 in my car and love it. It works VERY well. I don't have the jammer, but the detector works well. The laser portion of it isn't very good, but you're pretty much screwed with a laser no matter what you have. As some of the other guys have said, it has a very small beam, so it's hard to detect. But I've detected radar at a distance of about a mile and a half. And that's in town with lots of cars, trees, a few buildings, etc. between me and the cop. I've read on either radar busters or radar testers that on flat, open road like out in arazona and other places like that, that the x50 was at half alert 9 miles away from the radar. That's pretty dang good in my book.
